MODE OF SEPARATING EMBRQIDERIES.

SPECI ICATION forniing paft of Letters Patent No. 307,801, dated November 11, 1884-.

Application filed Sc-ptemLcr 8, 1883. (No spccimcnsa T0 all whom, it may concern.-

Be it known that I, ALBERT L. RICE, a resident of WVheeling, in the county of Ohio and State of WVest Virginia, have invented certain new and useful Improvements in Dress Trimmings and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention is an improvement upon Letters Patent No. 266,525, granted to me October 24, 1882, relating to the class of textile fabrics known as embroideries, edgings, and insertings. In said patent the rows of embroidery were rendered capable of being easily separated or torn apart by means of a line of perforations between the rows, which weak.- ened the goods so one portion could easily be torn from the other, in the manner of a sheet of postage-stamps.

The present invention consists of ruling the goods between the rows, either in a straight line or by a line following the contour or out line of the edge of the embroidery, with a fluid or ink composedof disintegrating substances that will operate to partially destroy the fabric where it comes in contact with the same; then in neutralizing or volatilizing the acid to prevent subsequent injury to the goods outside of the line, whereby the rows of embroidery can readily be torn from the roll or separated one from the other, as desired, without liability of tearing or otherwise injuring the same. y

In the drawings, Figures 1 and 2 represent bolts of embroidery.

The letters A designate the rows of embroidery; B, the ruling, (shown by a broad black line,) following the contour or outline of the edge of the embroidery; (l, the ruling, running straight between the rows and parallel with them.

I propose to rule the goods with'the disintegrating fluid by means of ruling-pens in a suitable frame, similar to that employed in ruling writing-paper. In the case of edgings, or where compound curved lines are necessary,

they can be ruled by means of rotary inking wheels or stencils.

To rule the goods with a fluid that will eat away the fabric along the line of contact, it becomes necessary that the chemical employed should be one that can be neutralized or eX- I hausted immediately after contact, to prevent future injury to the goods; and toaccomplish this I use adestructive fluid or ink composed of sulphuric acid 66 one part, water two parts; the acid diluted with one part water, starch sufficient to make thick, mixed with one part water, and the acid and starch combined. To this mixture is added sufficient gum-arabic to give it the proper consistency to run freely from the ruling-instruments, the proportions being changed to suit the class of goods upon which it is intended to beused and the ruling devices employed to apply it to the cloth.

Immediately after the fluid is applied the goods are passed over or between heated rollers or plates, which operate to neutralize or exhaust the acid in the fluid and prevent -it from spreading, thereby leaving a clear and distinct black line along the cloth, showing where the rows of embroidery can be sepa rated from each other. After this operation the goods are folded into bolts in the usual manner, and are ready to be placed on the market.

There are various other methods for neutralizing or exhausting the acid after it has produced the desired effect upon the line. One neutralizing method consists in the use of an alkali, either by immersing the line in a solution of alkali or by running aline of canstic or other suitable alkali over the acid line;

but, perhaps, the most practical method is by volatilizing the acid by heat immediately after it has been applied to the goods, as before stated. I do not wish to limit this last step in my invention to any one'of the foregoing methods, as either can be employed for exhausting the acid without departing from the spirit of the invention. Separating the rows in this way is especially serviceable in edg= ings which have a scallop or irregular edge, for it saves the labor of cutting around the edge by hand to remove the surplus material.

In some cases the bolt of goods can have a straight line of ruling between the rows of embroidery, and also have a line following the pattern or scallop on the edge of the embroidery, .so that one row can be separated from the other on either line, and the surplus cloth removed from the edge.

The principal advantage of this mode of preparing the goods so the rows of embroidery can be easily separated or removed from the bolt by ruling separating-lines with a disinte grating chemical fluid is, that the goods tear asunder or apart without injury, as the line of separation is uniform and regular, which is not the case where the goods areperforated, for frequently some of the threads are not cut away at all, and the result is that the rows tear across instead of lengthwise of the goods.

It is obvious that other acids or chemical compounds could be devised to accomplish the same result, and such I consider within the scope of my invention.

Having described my invention, what I ALBERT L. RICE.
